Wow- I'd really like to get my hands on one of those operating manuals for the L1200 Varipoint. I just got my hands on this enlarger from UCLA's Biology Department that was used gently for $400.00 but, alas, it came without a manual and even though I've used a Durst enlarger for a year, it was not this model. I'm lost- so very lost. And, something you said about opal bulbs caught my eye. What is that and why the switch?
I appreciate the time you've taken to compile this information and your overwhelming generosity.
